No, I think you're still #1 on the queue, Thermal. If I recall correctly, you've got 2 or 3 days after the end of Treehouse to start yours. TinCow is likely just opening sign-ups for Rubicon early so that he gets all the players he needs, in anticipation of the end of Council of Villains (which will, incidentally, be taking a little more than 3 or 4 days to finish off).
